the contents of a <a href="qtextblock.html">QTextBlock</a>.</p>
<p>A block consists of a sequence of text fragments. This class
provides a way to iterate over these, and read their contents. It
does not provide a way to modify the internal structure or contents
of the block.</p>
<p>An iterator can be constructed and used to access the fragments
within a text block in the following way:</p>
<pre class="cpp">
     <span class="type"><a href="qtextblock.html">QTextBlock</a></span><span class="operator">.</span>iterator it;
     <span class="keyword">for</span> (it <span class="operator">=</span> currentBlock<span class="operator">.</span>begin(); <span class="operator">!</span>(it<span class="operator">.</span>atEnd()); <span class="operator">+</span><span class="operator">+</span>it) {
         <span class="type"><a href="qtextfragment.html">QTextFragment</a></span> currentFragment <span class="operator">=</span> it<span class="operator">.</span>fragment();
         <span class="keyword">if</span> (currentFragment<span class="operator">.</span>isValid())
             processFragment(currentFragment);
     }
